: I have '97 Cosmos Black 1.9 Z3 in Japan.: I kept checking this messageboard, but I think this is something new.

: When I turn the ignition key one step forward while pressing the reset button of the odometer, you can see some data (numbers) shown on the odometer display.: Thenafter, WOW, see all these analog meters.

: I think it does not harm anything, and the same for all BMW makes.

: Can someone let me know what are the meaning of these displayed numbers?

: Just to make sure this is the process I did.: 1. Turn off the engine.: 2. Press the odometer reset button.(keep pressing): 3. Inset the key, and turn one step forward.: 4. See what happens.
